Morphological systematics of Leuctra duplicata Claassen, 1923 species group (Plecoptera:Leuctridae).

摘要

Adult males and females of Leuctra duplicata Claassen, 1923 and L. maria Hanson, 1941, the two proposed members of the L. duplicata group, were compared using standard light microscopy and scanning electron microscopy. Characteristics of the male paraprocts and female subgenital plate of L. duplicata are consistent across the broad range of this common species and allow for easy differentiation from L. maria. Distribution maps based on material examined are provided for both species.
